Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

    Comments about Bulbrite 12 Watt, 17 1/8 Inch T4 Cool White Fluorescent Bulb:

    I bought an office desk with an attached secretary. The light is hidden and worthless (out of date), the bulbs are hard to find, and not very cost effective. They burn out rather quickly (about 4 to 8 months useage) and that if used sparingly.
